OBD II Fault Code

In an effort to meet fuel and emissions standards, many manufacturers are utilizing cylinder deactivation systems. This system allows the engine's control module (PCM) to disable select cylinders when additional power is not needed from the engine, such as at idle or when cruising on the highway. If the engine's control module (PCM) determines that the Intake Valve for cylinder number four is not Turning on or off the way it is being commanded, the PCM will set code P3425.
